Formula

STH-NUPL = (market value − realized value) / market value = 1 − 1 / STH-MVRV.

How to read it

Positive NUPL indicates an aggregate unrealized gain under the model; a negative value indicates an aggregate unrealized loss. Values are displayed as a percentage of market value, rather than a return on acquisition cost.

Limitations

  • NUPL and MVRV express the same underlying relationship in different units. They are not independent confirmations of a trading signal.
  • On-chain movements include transfers between an owner's own wallets. They do not establish actual purchases, sales or investor identity.
  • The latest day is provisional. Data is updated daily; hourly resolution does not mean hourly publication.
